Washing powder is necessary for every household to wash clothes, but with the progress of the times, the emergence of various brands of washing powder has led to market chaos and misunderstanding of the use of washing powder. What problems should be paid attention to in the use of washing powder, and which of our use methods are wrong and even pose a health threat?
1. Scented detergent is not good.
Discrimination: correct
Most people who buy washing products consider “whether they are clean” and the second consideration is “whether the fragrance smells good”. However, the vast majority of perfume sprays are synthetic. 95% of their chemical raw materials come from kerosene, such as benzene and aldehyde. These substances may cause cancer and reproductive disorders, but more commonly, they cause allergic dermatitis.
2. Hand wash clothes without detergent
Discrimination: correct
After the skin is in direct contact with alkaline detergent for a long time, the weak acid environment of the skin epidermis will be damaged, and its effect of hindering the growth of bacteria will disappear, which may easily lead to skin itching, even allergic dermatitis and other symptoms, or leave pigment deposits on the skin. So when washing clothes by hand, you’d better use soap.
3. Washing powder can be used more than once
Discrimination: error
In life, many people regard washing powder as a “universal detergent”. In addition to washing clothes, they also use it to scrub furniture and floors, thinking that it has the function of decontamination, disinfection and sterilization. Unexpectedly, this may cause detergent to enter the human body. Experts suggest that even if the amount of washing powder entering the body is very small, it will cause poisoning. Do you dare to use more than one powder?
4. The effect of multi-functional detergent is good.
Discrimination: error
Many advertisements for washing powder claim to add some new formulas, which have more and stronger washing effects. These formulations mainly include surfactants, detergents and enzymes to achieve the purposes of easy dissolution, cleaning, softening, foaming and eliminating static electricity of clothes. But more substances are added to washing powder, which is not good for our health.
The commonly used detergent is harmful to human liver; Surfactants have long been found to damage the cuticle of the skin and cause rough skin, which has now been regarded as an important public hazard of polluting the environment; In addition to affecting the water quality, the alkaline substances contained in strong washing powder can also damage the human cell membrane and denature structural proteins: the organic chlorine and fluorescent agents contained in whitening washing powder are toxic substances, which can easily accumulate in the human body and cause harm to health.
5. Washing powder and disinfectant are the best partners.
Discrimination: error
When many housewives wash their clothes, they are used to adding disinfectant in order to eliminate bacteria. Some simply put detergent and disinfectant into the washing machine at the same time. In fact, this is not only ineffective in sterilization, but also harmful to human health.
Disinfectant is a kind of phenolic disinfectant containing chlorine. Excessive or incorrect use will also cause harm. The washing powder contains surfactants. If the washing powder and disinfectant are mixed, it is easy to produce chemical reactions and weaken their functions. In addition, if chlorine containing disinfectant is mixed with acid containing detergent, chlorine gas will be generated. When the concentration of chlorine is too high, it will irritate people’s eyes, nose, throat and other organs, and even damage people’s cardiopulmonary function and even endanger life.
Therefore, the normal washing method should be: add 3-5 drops of disinfectant into a bucket of water in the washing machine, or add water to make 1% – 5% disinfectant solution, Soak clothes and sheets for 30-60 minutes, and then use washing powder to wash them normally.
